OUTPUT RELAYS
page 1 of 5
Allows user to configure the three internal relays for output indication from the pump to a control
system, another pump or miscellaneous receptacle.
• The relays can be programmed Normally Open (NO) or Normally Closed (NC) and are rated for 24VDC @ 50mA maximum.
• Each relay is individually programmed (in Configuration) for each individual pump condition alarm and must be
“enabled” to function.
AVAILABLE PUMP CONDITIONS TO ACTIVATE RELAYS
Leak Detect
: Activates relay if a leak is detected and if Leak Detect is programmed in Configuration.
Run
: Automatically activates the relay when the pump is running.
Transfer
: Activates the relay to transfer operation from the primary pump to a backup pump.
– Automatically activates when a drive fault or loss of power occurs.
– Activates when Leak Detect is programmed in Configuration with the "stop pump" option selected and when a
leak occurs.
IMPORTANT!
– The primary pump's output relay must be wired to the backup pump's Standby input connection.
– The backup pump must be programmed in the same mode of operation as the primary pump.
– The backup pump must be powered by a circuit separate from the circuit powering the primary pump.
– The relay must be programmed as Normally Closed.
Tube Timer
: Activates relay when the pump run time is reached. The pump run time must be programmed
in Configuration.
Drive Fault
: Automatically activates the relay if the pump shuts down due to a drive fault error.
Standby
: Automatically activates the relay if a closed relay is wired into the Standby connection terminals causing
the pump to go into Standby.
Off
: Automatically activates the relay if the pump is turned OFF from the control panel.
Mode Change
: Activates the relay if the pump’s mode of operation is changed from the operator's selected mode
of operation.
OUTPUTS – SPECIFIC MODES OF OPERATION
Low Signal in 4-20mA or 0-10VDC
– Activates the relay if the input signal falls below the value programmed in the control mode.
High Signal in 4-20mA or 0-10VDC
– Activates the relay if the input signal rises above the value programmed in the control mode.
Low Flow in Hall Effect
– Activates the relay if the process flow falls below the gpm or lpm programmed in the control mode.
High Flow in Hall Effect or PPM Feed-Variable
– Activates the relay if the process flow rises above the gpm or lpm programmed in the control mode.
Signal Overrun in Pulse
– Activates the relay if the pump receives an input signal leading to incorrect dosing.
Repeat Pulse – Manual, 4-20mA, 0-10VDC, Pulse, 7 Day Timer, PPM Feed-Constant or Cycle Timer
– Automatically activates the relay when the pump receives the dry contact input signal to repeat this signal to
another pump or device.
